Question

b,
A hollow cylinder (m, R) rests on smooth horizontal surface. A
bullet of same mass m moving with velocity V strikes cylinder
tangentially and gets embedded in it.
{ mark correct option (s) m
(a) energy of system (cylinder + bullet) is conserved
b) Momentum of system is conserved
(c) l' of system is conserved about any point in the plane of
cylinder
(d) 'L' is not conserved due to torque of mg​

Answer 1

Answer:

PHYSICS

A circular hoop of mass m and radius R rests flat on a horizontal frictionless surface. A bullet, also a mass m and moving with velocity v, strikes the hoop and gets embedded in it. The thickness of the hoop is much smaller than R. The angular velocity with which the system rotates after the bullet strikes the hoop is:
